4) photoelectricity timing method
光电计时法
1.
In order to enhance the accuracy and the stability for measuring moment of inertia through the torsion pendulum method,it is demonstrated in principle the measuring position error can cause the period measurement error in the measurement of the period of torsion pendulum using the photoelectricity timing method,but the measurement error can not be reduced by multi-average.
为了提高扭摆动法转动惯量测量精度和测量稳定性,从理论上证明了采用光电计时法测量扭摆动周期时,测量位置偏差会引起周期测量误差,而利用多次周期平均的计算方法不会减小测量误差。
